Every time it rains, it starts leaving my garage. I run thru a few small water puddles, turn left or right onto a street and the power steering goes out. My wife almost went up the curb and on the sidewalk, she can't muscle it, and I struggle to muscle it. Once you get going the strange noise goes away and the steering comes back. It's been to the shop where I bought it twice,( Sheboygan Auto) its been covered by GMC each time. The dealer doesn't have a clue. It's like water splashes up and F©®™ everything up!! Only put about 8000 miles on it since I got it last Dec 2014, hasn't even been a year yet. This is buy far the worst purchase ever, getting ready to bale out of this pile of crap!!

My husband and I purchased this 2008 Acadia in January 2012 (used of course) with 80,000 miles already on it. It had only had one owner prior to us. Loved this SUV until this last January. I thought the current problems I was having may have been from doing $9,000 in damage from hitting a deer in December but after doing some research I realize that is not the case. On several occasions while trying to pull into or out of a parking stall I have lost all power steering. It does regain after a few moments. No warning lights and such have come on in the past. I have had it in the shop a few times to have the pump checked with no obvious problems i.e leaks, low fluid levels, etc. More recently I have lost my power steering while driving at speeds around 20mph. This mainly occurs when I am trying to make left hand turns but has also been happening with right hand turns. Took it in to the shop again a few days ago and the mechanic suggested that we replace the pump. Cost $900. He then told me that it may also be the rack and pinion which would be around $900 as well. I guess we aren't the only ones having problems with our GM because he said he had a gal in there a few weeks ago with a Yukon that was doing the same exact thing!
